Specification of Letters Patent. Patented July 30, 1918.

Application filed July 1, 1911, Serial No. 636,402. Renewed December 7, 1915. Serial N0. 65,638.

To all whom it may concern:

Be it known that I, FRANKLIN W. OEHRLE, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Machines for Making Ornamental Rope or Cord, of which the following is a specification.

My invention has relation to machines employed in the manufacture of ornamental rope or cord of the character in which a plurality of loops or strands are secured between binding threads, the said loops extending around one of the said threads and the body of the loops extending in the form of a continuous spiral longitudinally of and around the said binding threads.

The nature and purpose of my invention will become apparent from the detailed description thereof taken in connection with the accompanying drawings which illustrate a convenient embodiment thereof, but it will be understood that changes in the details of construction Within the scope of the claims may be made Without departing from my invention.

In the drawings Figure 1 is a view partly'in section and partly in vertical and longitudinal section,

Fig. 2 is a view of the rear-end of'the mechanism embodying my invention;

Fig. 3 is a view in elevation of the rear end of the former with certain parts associated therewith; and

Fig.4 is a longitudinal vertical section of the former with a portion of a cutting member shown in proper cutting position with relation thereto.

For the sake of simplicity, I have omit-- ted from the drawings all those parts of the mechanism which are not essential to my invention, such, for instance, as the rack, preferably located at one end of the machine upon which the spools are supported from which the threads or strands which make up the ornamental loops of the ropes or' parts may be referred to standard at the right handside of Fig. 1 to and through the bearing in the upright or standard 2. v r

10 designates a gear Wheel secured by means of. the binding screw 11 to the revoluble member 6. 5 Revolution of the gear I wheel 10 (by means not, illustrated) causes revolution of the revoluble member The speed of revolutionmay be such as desired.

12 designates a guide orguiding member for the inner binding thread 13 which guide member issupported upon plugs 14' and 15 secured in the revoluble member 6 and which guide member is :held against longitudinal movement by means of the collars 16 secure upon opposite sides of theplug 15.

The inner binding thread 13 is taken-from the thread 'upona spool 20, preferably fast upon a sleeve 21, which isloosely and revolubly mounted upon the revoluble. member 6. The thread passes from the Tspool 20 through loop guides 22 on one arm of the flying arms 23 secured to the revoluble member 6. r The purpose of providing two such arm is to maintain the balance of the said revoluble member. The thread passes from the guides 22 through an eye or opening 24 in the revoluble member and thence "to the guide member 12.

The revoluble member 6 revolves in the direction indicated by the arrow 25 in Fig. 2 of the drawings, and the thread upon the spool 20 is so wound thattin being drawn therefrom the spool is rotated in the same direction. By reason, therefore, of the con nection of one of the flying arms 23 with the thread which is drawn from the spool 20, the spool is caused to revolvewith the revoluble member 6 and in addition thereto is given an additional speed of rotation or revolution by the drawing off .of the binding thread 13 by means of the twister hereinbefore referred to but which is not illustrated.

In order to prevent the spool 20 from overrunning itself and for the purpose of controlling its revolution, I have provided the brake band or cord 27 which is connected at 28 to the frame of the machine and extends from its point of connection over a groove 29 in one flange of the spool and its opposite end is provided with a weight 30 as illustrated in Fig. 2 of the drawings.

The loop strands or threads 31 which may be of any number as desired and which may be of any suitable and desirable material and of any color desired, are taken from spools which are supported upon spindles upon a. rack not shown.

It will be understood that except for the fact that the spools are revolved for the purpose of permitting the thread to be unwound therefrom, they are stationary so that when the thread has been removed from one spool it may be replaced by another without stopping the operation of the machine or in any way affecting the operation of the mechanism illustrated in the drawings and constituting my invention.

The loop strands are guided or conducted through the thread or strand guiding tube 34 which is supported in the plugs 33, 14 and 15 in the revoluble member 6 and is arranged in parallel relation to the axis of said revoluble member. It is revolved bodily around the axis of the said revoluble member but is held against independent rotation or revolution about its own axisby reason of its connection at '35 with the upper end of the link 36 pivoted at-37 to the lever 38 pivoted at 39 to a part of the frame of the machine.

This construction differs from that illustrated in my co-pending application, filed July 1, 1911, Serial No. 636401, in which the rear end of the guide member for the loop strands or threads is held in substantially stationary position.

In the present construction the rear end as well as the remainder of the guide member 34, travels through a circulatory reciprocating path.

Notwithstanding the fact that the member 34 revolves around the axis of the revoluble member 6 as well as around the member 12 it does not interfere in any way with the inner binding thread 13 for the reason that the said thread and the spool from which the same is drawn is caused to revolve in the same direction and with the same speed as the said member 34.

4O designates a tubular former having a head 41 which is provided with notches 42 and 43.

The inner binding thread 13 passes through the guide member 12 and through the notch 43 as indicated most clearly in Fig. 3 of the drawings and along the underside of the cylindrical portion of the former 40.

The loop strands or threads which pass through the guide member 34 extends from the forward end of the said member 34 and are wound around the stationary former 40 by reason of the revolution of the member 34.

The binding thread 13 is included within the coil of the said strands or threads 31 and are held between the same and an outside binding thread 44 which is supplied from a source of supply not-shown and extends around a sheave or roller 45 and is carried into close proximity to the outer side of thecoil or threads around the former 40 and in opposite relation to the binding thread 13. The forward ends of the said binding threads are connected to a twister (not shown) which is of known construction and operates in a known manner and the said threads together with the ornamental strands or threads which are held between the binding threads aredrawn or fed forward and simultaneously twisted. An important function of the roller 45 is to feed the coiled ornamental-threads and the binder threads forward and at the same time control the forward movement of said threads.

As an additional means for causing a positive forward movementof ornamental threads on the former I have providedthe endless cord 47, which may be of any suitable material, which extends through the tubular former 40' and around the guide rollers 48 and then in reverse direction through the notches 42 and along opposite sides of the said former'40. Fhe ornamental-strands or threads are wound around the said cords which extend along the-opposite sides of the former 40 and the travel of the latter in the direction indicated-by the arrow in Fig. 1 of the drawings causes the said threads which are coiled around the said former to be fed forward against the cut ting knife 50 which preferably is circular and a portion of the edge of which projects into a slot 51 formed in the upper sideof the said former, as indicated most clearly in Fig. 4 of the drawings. The edge of the said knife is located in-contact with the wall forming one-end of the slot 51 as is indicated at 52 so as to prevent any of the threads which are to be cut by the knife from passing between the edge thereof and the edge of the end wall of the said slot. The cutting device is made-circular in order that when one portion thereof becomes dulled another portion thereof may be brought readily into cutting position.

The cutting member 50 is supported in any suitable manner upon an adjustable bracket 54 which is supported upon a stationary bracket 55. The former 40 is also supported uponthe said bracket 55'as is indicated at 56.

In this construction, as in the construction illustrated in my copending applications, the binding thread is taken from the spool 20 in untwisted condition but in the operation of the device such thread is twisted between the said spool and the point of its connection with the outside binding thread 44.

Having thus explained the nature of my said invention and described some of the ways of making and 'using the same although without attempting to set forth all of the forms in which it may be made or all the modes of its use, what I claim is 1.
